Law Enforcement and Public Safety Service (Hungarian "Rendészeti Biztonsági Szolgálat") is a part of the Hungarian National Police which is very similar to Western-European Gendarmerie-type police forces.
Therefore, control of state highways, riot police assignments and messenger assignments between police services belong to the sphere of authority of RBSZ, but its sphere of authority is much wider.
The uniform of the RBSZ is often different from that of traditional Hungarian policemen; they are much more soldier-like, therefore they can often be recognised.
However, regulation is not so strict, which is why one might see RBSZ-policemen in traditional uniforms; for example wearing baseball hats, in which they are less soldier-like.
It must be mentioned that although RBSZ are the police force in Hungary that is similar to Western-European gendarmeries, there is a special police force in Hungary, the independent Border Guard Service (also subordinated to the Ministry of Justice), that has squads the members of which are trained as soldiers and in case of war they get subordinated to the Army and the Ministry of Defence.
